Labels and Axes

If your viewers are going to understand your chart, they have to be able to interpret the data on it. It's easy to create a beautiful chart that conveys no information at all except for the fact that you really have a knack for picking fill patterns.

To ensure your chart makes sense, see that it's well-labeled and the values assigned to the various data series can be easily deciphered. That's where formatting axes and adding labels becomes important.
